Io allwitom it may concern: Be itknowntha't I, WH LIAM J. OHAIRE, a citizen of the United-States, residing at Washington, in the District of Columbia, have inventedcertain new and useful Im rovements in Submarine Boats; and I dodec are the following to be a full, clear, and exact descri tion" of the invention, such as will enab e improve others skilled in the art to which it appertains V theinventionconsists of certain novel fea-- tures of construction, combination, and a1: ran ementsof parts, as will be hereinafter de- SOIlEGd and claimed. 1

In the'accompanying drawings, Figure 1 is a side View of a submarine boat, showirig the application of the invention thBI'BtOa. ig. 2 is an enlarged vertical sectional view through the ventilator and a portion of the boat; and

Fig. 3 is a detail side elevation of the hollow float, showing the manner of attaching'the' fioat-securing nuts or blocks to the side of the fioat.-

Referring more Earticularl to the drawings, 1 denotesthe oat,whic may be of the usual or any desired construction. On thetop A. or deck adjacent to the front and rearv ends of the same are arrangedhousings 2, in which'are formed seats 3 to accommodate hollow floats a, which arepreferably spherical,but which may be of any suitable shape. Connected to the lower' side. of the float 4 is aswiveled or revolubly-mounted ring 5, and tothe top ofthe boat, within the housings 2, is a swiveled, 1 or revoluhly rnounted ring 6, said rings-5 and 6 being connected by two-or more chains 7 of.

suitable len th, whereby the floats are se-- cured to the oat and allowed to float on the surface of the water. Arranged in the bottom of theflo'at islet-threaded hole, into which is adapted to be screwed a short section of metallic tubin'g S, the u per end of which projects into tl-ie'float, an 'to the lower outer end of which. is connected, by means of a ballimd-socket joint 9, an outer flexible tube 10,

said tubebeing connected at its lower end by Specificationof Letters Patent.v

means of a ball-and-socketjoi'nt 12 to a short section of metallic tubing '13, which is adapted to be screwed into enga ement with the to of the boat within the ousin s 2, said tu in 13 extending-into the boat or a suitable istanceand having in its extended end a' valve 14. Within the outer tube 10 is arranged a small inner tube 15, the u per end of which projects through the side 0 the metallic tubing 8 and into the float, as shown. The lower end of the inner tube projects through the metallic tubing 13 and into the boat and is provided with a valve 16. Around the outer flexible tube are arranged atsuitable intervals rings or collars 17, which are connected to the chains 7 by short links 18,

thereby bracin' said tubes and preven ting the same from ecoming twisted ortan 'led,

On the lower end of the short metallic tuliing 'within the boat areformed screw-threads,

and to said threaded end is connected a pump 19, by which'air is drawn through the tube and-into the boat. The tube 15. ermits vitiated air to be discharged from the boat and may be connected to t e pump and used for supplying the air to theboat in the event thatthe outer tube 10 becomes injured. 1 1

formed an air inlet opening 20, which is adapted to be opened and closed b means of a door or valve 2 1 flwhich is hinged y connected tothe top-of t e fioatjas shown. To the inclined arm 22, to which is loose 'In the top or upper. side of the float is {door is connected'a downwardlly-projectin' v yconne'cteu a short operating-rod 23, said rod being.

adaptedto work through a stuffing-box arranged in the side of the fioat. 4 Gonnected to the lnnerend of said rod 23 is an operatingrop'e. 24, by which the door or valve 21may" be opened. To the door. is also connected the up er end of a rope 25, which works throng I the opening 20 and'is. adapted to closethe door: The ropes 24 and 25 arerun through'the outertube 10 and pass out of the same throu h a threaded nipple 26, formed on the metallic tube 13 within the boat. on the threaded outer end of thenipple'26 is screwed a yoke27, in which is mounted a screw-plug 27, adaptedsto be'screwed into the nipple 26 to close the aperture therein a through which the cords 25'pass out-of the tube 13.

I65 When-the boat is floating on'the surface of o erated from within the boat.

t readed ends of the screws are adapted to screw into the threaded apertures ofnuts or blocks 31, which aresecured to the, lower opposite sides of the float, by means of annular flanged strips 32. When the floats are secured in the seats 3, the chains 7 and the air-L tubes 13 and 15 are disposed within the housin s 2. The housings are provided with suitab y-closed manholes 33, through which the chains and tubes may be arranged'therein, and with drain-cocks 34, b means of which the Water may be drained t erefrom.

The-chains 7 are somewhat shorter in length than the air-tubes, thereb' relieving I the latter of all strain when the cats are in screws 28. v r

, On the top or deck of the boat are arranged use. The loose connection of the tubes and chains with the floats and boat permits the floats to move freely in all directions and to revolve. r p

In Fi 3 of the drawings is shown the manner in w hich the blocks or nuts 31 are inserted in the annularflanged stri s 32, said strips having formed therein a breal-i through which the blocks areinserted.' The blocks are pre-. vented from slipping out of said flan ed strips by means of set-screws arrange therein, as shown. By thus attaching the blocks to the float they may be readily shifted to bring them into position to be engaged by the 7 one or more windlassesBfi, by which the floats may be handled to seat the same properly in the o enings of the housings 2;

A oat rovided with alr-suppl 'ng mech anism suc as herein shown an described ma remain submerged for an indefinite pe rio of time without danger of the occupants being suffocated, It will be understood,

for usehowever, that the device is intended 0111 in case of an emergency. I U I I iom the fore oing description, taken in connection witht e accompanyin drawings,

the construction'and operation 0 the invention will be readilyunderstoodwithout re quiring a more extended ex lanation.

Various changes in the orr'n, proportion,

and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention. t Having thus described my invention, what I claim as new,=' and desire to secure ,by Let ters Patent, is l '1.
